Filter by:To implement a new method of performing chest CT imaging in young children at Packard Children's Hospital entitled controlled ventilation infant/young child chest CT scanning. This technique will be used to evaluate early lung disease comparing quantitative chest CT air trapping and airway measurements with lung function measurements in infants, toddlers, and young children with chronic lung disease.
In response to the European regulatory authorities, GSK is conducting a post-marketing observational study to assess the efficacy of Relenza when used as prophylaxis against influenza. SPECIFIC AIMS 1. Determine the frequency of patients who received Relenza from October 2006 through April 2009, and among them the number who have no concurrent diagnosis of influenza, i.e., those receiving Relenza for prophylaxis, and among these the number who have a family member with a medical visit for influenza within three days preceding the above indentified patient's dispensing of Relenza. This is to determine the feasibility of conducting detailed analysis. 2. If analysis is feasible then tabulate the frequency of influenza-like-illness and respiratory outcomes in users of prophylactic Relenza and their family members and in family members of persons using Relenza for the treatment of influenza (i.e., index cases). 3. If analysis is feasible then estimate the direct effect of prophylactic Relenza on the occurrence of influenza-like-illness and respiratory outcomes, the secondary effect of Relenza treatment of influenza on susceptible family members, and the total effect of Relenza (treatment plus prophylaxis). METHODS Overview of Study Design This is an analysis of the 30-day risk of influenza-like illness and respiratory outcomes in persons for whom some household members (index cases) have had a medical visit associated with a diagnosis of influenza. The exposed individuals to the index case will be categorized into one of four cohorts according to whether the exposed person received prophylactic Relenza or no antiviral treatment and by whether the index family member with a diagnosis of influenza received antiviral treatment. Estimates of the direct effect of Relenza prophylaxis, the indirect effectof preventing disease in susceptible family members, and the total effect of disease reduction when both index cases and susceptible family members are treated will be obtained from different comparisons between cohorts, as outlined below. The research will cover the first three influenza seasons during which Relenza has been indicated for prophylactic use in the United States. These will be from October through April of 2006-2009.
Introduction: With the rapid development in technology telemedicine has become a tool with the potential to improve and optimize the treatment of different diseases and to make diagnostics, treatment and counseling possible over shorter or longer distances. Home based telemedicine is a new method that leads to a series of important questions that needs to be answered. This study is designed to answer questions concerning patient safety in telehomecare, the patients´ quality of life, efficiency and a cost benefit analysis of implementing this technology. This study is about patients with chronic obstructive pulmonary disease (COPD) who are admitted to the hospital with an acute exacerbation. Approximately 24 hours after admission half of the patients are randomized to be admitted to their own home supported by telemedical equipment while the other half remain admitted at the hospital (typically between 5-7 days). Primary Aim: To investigate if telemedical surveillance and treatment in the recovery period of an acute exacerbation is just as safe as conventional admission of patients with COPD measured on treatment failure. Secondary Aims: To evaluate if telemedical surveillance and treatment in the recovery period of an acute exacerbation compared to conventional treatment of COPD: 1. Is comparable in reestablishing Forced Expiratory Volume in 1 second (FEV1). 2. Demands the same number of treatment days/time before discharge/cessation of telemedical surveillance. 3. Is comparable in quality of life in the two groups of treated patients. 4. Have comparable adverse event profiles. 5. leads to a lower total cost in health services (health economical analysis) 6. Is possible to do for the patients (drop-outs because of the technical equipment or the patient does not know how to use the equipment.) 7 Is better seen from the physician's perspective when it comes to: 1. The virtual patient contact / communication 2. Technology 3. The work process compared to the conventional work process 4. Time spent with the patient 5. Usability 6. Improvement potentials ("the doctors view") 8. The equipment is satisfactory for the patient to use Method For this study a telemedical platform has been developed on which it is possible to treat patients in their own homes. The platform consists of a videoconference part that allows the patients to make contact to qualified medical staff and a technology part that can transfer vital indicators of the patients´ health condition (lung function, oxygen saturation, pulse etc.) 175 patients will be included with an expected drop-out of 20 % or 35 patients. The patients will be equally recruited from two hospitals (Frederiksberg and Herlev Hospital). All patients must have an exacerbation in their COPD that requires hospitalization to be included in this study. Each patient participates in the study for 6 months after discharge with follow-up at 1, 3 and 6 months.
The primary objective of the study is to evaluate the efficacy of Helium/Oxygen (He/O2) 78%/22% compared to a conventional Air/O2 mixture in reducing endotracheal intubation rate and mortality in patients with severe hypercapnic exacerbations of Chronic Obstructive Pulmonary Disease (COPD) during their index Intensive/Intermediate Care Unit (ICU) stay.
There is a rare condition causing scarring of the lungs termed interstitial lung disease. This comprises a group of conditions which can be divided into separate diseases. The aim of this study is compare a group of patients (the cases) with 2 types of this disease (fibrotic non-specific interstitial pneumonia (NSIP) and idiopathic pulmonary fibrosis (IPF)) with patients without the disease. The study will look at the 2 groups and their exposures to factors such as medications, smoking, previous jobs, previous medical problems and specifically heart disease and any operations or procedures involving the heart. There have been previous studies showing a link between heart disease and scarring of the lungs. This study will look at whether this association is stronger in one or the other type of lung scarring diseases.
The ability for patients with COPD to exercise is limited due to the deterioration of their lung function. NVA237 is being developed to treat COPD. This study is designed to look at how well NVA237 improves the ability to exercise in patients with moderate to severe COPD.
The purpose of the study is to find out if AZD2423 can reduce inflammation in the lungs of patients with mild COPD.
To validate the capability of the Respironics Synchrony ventilator to properly detect Expiratory Flow Limitation (EFL) as compared to the gold standard method of detecting EFL via the Mead and Wittenberger technique.
Chronic obstructive pulmonary disease (COPD) is a condition of the lungs which results in breathing difficulties due to the lungs becoming inflamed and the airways narrowed. Current treatments have focused on opening up the narrowed airways but, in addition, we know there is increased inflammation in the blood and these patients are at increased risk of heart disease. Statins, simvastatin being one of them, are drugs used to lower cholesterol in the blood but may also reduce inflammation and lower the risk of heart disease. This study will explore whether simvastatin reduces one of the risk factors in patients with COPD in a short term proof of principle study. The key purpose is to determine whether simvastatin improves the pressure and stiffness of the main blood vessels namely the arterial stiffness measure of aortic pulse wave velocity (PWV). In parallel, we will describe changes in airways and / or blood inflammation and change in breathing ability
Chronic obstructive pulmonary disease (COPD) is number four of the leading causes of death in the USA and Europe. Moreover, among the top five causes of death, this disease is the only one with increasing mortality rates. Physical training has become an evidence based therapeutic intervention in these patients. In this study the investigators aim to establish if supplemental oxygen during strength and endurance training improves exercise tolerance. Furthermore, the investigators want to research, if supplemental oxygen has the ability to increase training intensity, which would lead to a greater training effect with respect to respiratory, vascular, inflammatory and anthropometric parameters, as well as quality of life. SCOPE is a prospective, randomized, double-blinded, controlled, cross-over trial. The investigators aim to enroll 40 patients suffering from COPD aged >30 years. Inclusion criteria are FEV1 30-60%, and PO2 at rest >55 mmHg. At baseline, patients will undergo pre-tests including pulmonary, exercise physiological and medical investigations. Prior to the exercise training, an intervention-free control period with usual care is planned. This will be followed by 2 x 6 weeks with physical training (ergometer based endurance training and strength training, using weight lifting machines) with either supplemental oxygen or usual room air (e.g.: first 6 weeks of exercise with oxygen supplementation followed by 6 weeks of room air). After the initial control period and between these two exercise periods, patients will be tested as described in pre-tests, and at the end of the second exercise training period. In addition, the investigators will assess changes in lung function and symptomatic dyspnoea, as well as in quality of life (St. George's Respiratory Questionnaire). Within this study, the investigators hope to improve rehabilitation programs for COPD patients.
